The International Symbol of Access (ISA), also known as the International Wheelchair Symbol, denotes areas where access has been improved, mostly for those with disabilities. It consists of a usually blue square overlaid in white (or in contrasting colours) with a stylized image of a person in a wheelchair.[1] It is maintained as the international standard ISO 7001, image of the International Commission on Technology and Accessibility (ICTA), a committee of Rehabilitation International (RI).[2]
